Accompanying drawing has provided the structural representation of the utility model embodiment.
Fig. 1 is the Movable center points plan view;
Fig. 2 is the A-A section revolved view of Fig. 1;
Fig. 3 is the B-B section revolved view of Fig. 1.
Among the figure: 1. track switch 2. hearts 3. wing rails 4. slide bars 5 of living that integrate with, wing rail and track switch the integrate with flex point of junction and the horizontal plane that line 6. bodies 7. shoulders cooperate the perpendicular 11. nut 12.L shape fitting faces of inclined-plane 8. pull bars, 9 rocking arm 10.L shape fitting faces thereof
The utility model is described in further detail below in conjunction with embodiment.
Embodiment changes a social system on the basis of existing railway Fixed frog, and its basic structure, overall dimensions, weight is broadly similar with it.Track switch on the former Fixed frog body 6 integrates with 1, all maintain the original state with the wing rail 3 that links of integrating with etc.The slide block that can slide at body upper edge horizontal plane 12 in top is made in the two isosceles triangle tips that integrate with and intersect to form between wing rail; This locates the surplus part of body institute to L shaped, and on it, side surface cooperates with slide block soffit and respective side, L shaped cooperation side is to be parallel to track switch to integrate with and connect the perpendicular 10 of flex point 5 lines with wing rail.Slide block is when the original position of not slippage, and side of its isosceles triangle and bottom surface prolong the back, side and 3 spaces of being contained of adjacent wing rail thereof are all filled up by this slide block extension in addition with triangle; Wherein only the corresponding ramp 7 that stretches out shoulder of this side of inclined-plane and slide block of wing rail top below contact, conduct locatees fitting face; Consistent therewith, other side of waist of slide block triangle also should be shaped on the shoulder 7 that can cooperate with other location, inclined-plane, flank rail inside top below, forms the main shape of the heart 2 alive that slides.The two drive link slide bars 4 that have a step with, surface parallel with the slide block glide direction pass the slip that has the respective step hole the live heart 2 and corresponding wing rail 3 and even track and the cooperation in two step bars holes is fixed by nut 11 and threaded step-like slide bar 4.The drive link that links with two bars links through the operation drive disk assembly pull bar 8 of rocking arm 9 with this track switch switch blade of control.It more than is the simple scenario of this routine structure.
During use, the switch blade on this turnout need be moved the operating position according to operation, and Lian Dong drive link makes slide block also shift to same direction with it, above in Fig. 1, and by the inclined-plane location of this side stage shoulder with wing rail.Because slide block itself has been filled up whole spaces between this side and wing rail, make the heart 2 connection that continues of living by sliding of the vacancy of two groups of track switches between integrating with, there is not the existing vacancy of Fixed frog; And limit by wing rail and the face of being slidingly matched, make track connect reliable, accurate positioning.If the operating position of switch blade is at opposite side, the shackle rod 8 of then through transport with it will make the heart 2 alive shift to below among the figure.The design of transmission should guarantee that the slide block heart of living puts in place, and locating surface can guarantee accurate location, and inclined-plane, drive disk assembly and be slidingly matched and make slide block closely be pressed to body provide good user mode.Clearly, by such track switch, vehicle does not have top rolling, vibration and the noise that produces because of track switch, and what make that track switch no longer influences vehicle passes through speed and running comfort.Do not had the influence of track vacancy, operational vehicle just can not produce lateral force at the place, turnout, just can save the former guard rail that is located at the track switch outside yet; Can not take turns simultaneously yet to by the time interference.
